and 2 cheap spares which I'll probably never use.

All I can say is my Wasabi batteries worked well for 2-3 years. I used the external charger that came with my K-3 mk 1 and never had any issues.
What I have learned from the forum about the lack of internal temperature sensor is that I will never charge them inside the mk III body. Good luck.

I've used wasabi and kaster batteries in my K-S2 and K-70 and they've worked well and still are after 2+ yrs. I've only charged them in the Pentax charger (which is the only charger had). I'll use them in the K-3iii also, but I'll have 3 Pentax OEM batteries also that I'll use primarily (one in the body and one in the grip). The wasabi batteries will back those up maybe when I forget to charge the Pentax batteries. Usually I rarely use up 2 batteries in one day. I'm not worried about using the wasabi batteries, just the charger, which I'll probably not use anyway.

I can't say for the K3III, but neither my K5 nor my K-1II came with any film on the screen. Hopefully someone who've bought a K3III can answer.

Thanks!
